Distinguish between (A) real and pseudo foeces (B) consevative and non conservative forcea (C) contact and non contact forces (D) inertail and non-inertail frames of reference
Answers
Answer:
real force exist in nature where are the pseudo force is just an imaginary force. pseudo forces are just to explain some phenomena. for example centrifugal force is an imaginary force which is just to explain the phenomena such as motion of object in outward direction in a circular motion.conservative force are those forces in which the work done in a closed path is zero a non conservative force is a force in which work done in a closed path is not zero. inertial frames are are those frames in which Newton laws hold completely where as in non inertial frame of reference Newton laws do not hold completely.
Answer:
A real forces which exist in nature but a pseudo force is a force which is actually a resultant of real forces like centripetal and centrifugal for example a stool is tied with a massless string then it is rotated in a horizontal circle by a person then tension force acting on on the stone act as a force which will accelerate stone towards the centre and to explain this phenomena in ground frame terms like pseudo force is used but actually it is tension force which accelerates the body towards the centre , examples of some pseudo forces are centripetal force and centrifugal forces and examples of some real force are normal reaction force ,weight electrostatic force
conservative forces are those forces who's net worth done depends upon final and initial position not on the chosen path example work done by gravity and non conservative forces are those forces whose net work done depends upon the path chosen example friction force
inertial frame of reference are those frame of reference which are moving with same velocity or are at rest with respect to a system which is observed while non inertial frames are those frames which are accelerated with respect to the observer system
contact forces forces with body only when a body is in contact with the surface example normal reaction force and friction force non contact forces are those forces which can act on a body independent of contact with the surface or a particle examples are gravitational force electrostatic force and magnetic force
